This study is a randomized trial examining the impact of expiratory muscle strength training (EMST) on maintenance of safe and efficient oropharyngeal swallow function in persons with cancer of the head and neck (HNCA) undergoing treatment with radiation therapy or chemoradiotherapy (RT/CRT).
Thirty (30) persons with newly-diagnosed HNCA who will be treated with RT/CRT will be randomized to an 8-week program of either Active Expiratory Muscle Strength Training (EMST) + Standard Care or Sham EMST + Standard Care in order to examine the impact of EMST on swallowing function. The training program will consist of 5 sets of 5 breaths, 5 days per week for 8 weeks, coincident with RT/CRT. Patients randomized to the Active EMST group will use the EMST150 (product name) expiratory muscle strength trainer according to package instructions. Those randomized to the Sham EMST group will use an EMST150 device that has been modified to eliminate resistance to airflow.
All subjects will be evaluated prior to initiation of cancer treatment (baseline assessment), 4 weeks into cancer treatment and again at the completion of cancer treatment (8 weeks after initiation of treatment). Assessment will include measurement of maximum expiratory pressure (MEP), a videofluoroscopic swallow study (VFSS) to objectively document swallow function, and administration of swallow-related quality of life (QOL) questionnaires.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Active EMST + Standard Care | Experimental | Patients randomized to the Active EMST + Standard Care arm (ACTIVE) will use the EMST150 device as packaged, i.e. following package instructions with a device that has its valve spring maintained. |
|
| Sham EMST + Standard Care | Sham Comparator | Those randomized to the Sham EMST + Standard Care arm (SHAM) will use an EMST150 device that has been modified by removing the internal spring, which allows the valve to open in response to airflow through the device regardless of the amount of pressure generated. |

| EMST | Other | Expiratory muscle strength training (EMST) is an exercise program designed to strengthen the muscles of expiration by increasing expiratory load during breathing exercises using either resistive or pressure threshold devices. The EMST150 is a commercially-available device considered non-significant risk (NSR). The EMST150 device will be used for this study. |

| Feeding-tube-free food intake (days) | the number of days from the beginning of the study until change in feeding status from 100% oral intake to combined oral intake and tube intake and/or 100% tube feeding will be calculated | 8 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Penetration-Aspiration Scale rating (number) | From Videofluoroscopic Swallow Studies (VFSS), change in Penetration-Aspiration scale score will be determined from baseline to mid-treatment to post-treatment. Penetration-Aspiration Scale is an 8-point ordinal rating scale. | 8 weeks |
| Timing of Aspiration (category) |
| Measure | Description | Time Frame |

Subjects will not know whether the device that they are given has a functioning valve spring or whether the valve spring has been removed.
Researchers assessing the outcomes will not know the arm to which the subject was randomized.

From Videofluoroscopic Swallow Studies (VFSS), timing of aspiration will be determined from baseline to mid-treatment to post-treatment. Timing is identified as a category, either before, during, or after. |
| 8 weeks |
| Presence of pharyngeal residue (dichotomous) | From Videofluoroscopic Swallow Studies (VFSS), the presence of residue in the pharynx (yes or no) will be determined from baseline to mid-treatment to post-treatment. | 8 weeks |
| Extent of hyoid movement (mm) | From Videofluoroscopic Swallow Studies (VFSS), the change in extent of hyoid movement in mm will be determined from baseline to mid-treatment to post-treatment. | 8 weeks |
| Upper esophageal sphincter (UES) opening width (mm) | From Videofluoroscopic Swallow Studies (VFSS), the change in width of UES opening width in mm will be determined from baseline to mid-treatment to post-treatment. | 8 weeks |
Change in scores on the M.D. Anderson Dysphagia Inventory (MDADI) will be calculated from baseline to mid-treatment to post-treatment. MDADI consists of four ordinal rating scales with scores ranging from 0 to 100 with higher score reflecting better function. |
